This type of robot is usually equipped with high-performance sensors and advanced control systems, which can accurately process the surface of the workpiece to ensure the quality and consistency of the product. Before using the polishing and grinding robot, it needs to be programmed and debugged in detail. The user needs to set the robot's motion trajectory, polishing pressure, rotation speed and other parameters according to the characteristics of the workpiece and the polishing requirements. After that, the robot can automatically complete the polishing and grinding work, and the process can be monitored and adjusted through the control system.

[0003] During the use of the existing polishing and grinding machine robot arm, it is not convenient to detect the position of the clamping component, and it is not convenient to correct the use position of the clamping component. The metal material to be polished may move during the polishing process due to insufficient clamping force or the thrust of the polishing component. The movement of the metal material position is likely to affect the polishing accuracy. The robot arm may not be able to accurately track and correct the deviation on the polishing path, which may lead to uneven polishing or insufficient polishing. In order to solve this technical problem, the utility model proposes a polishing and grinding robot arm with automatic correction. Utility Model Content

The No. 1 cylinder 4 and the No. 2 cylinder 7 can flexibly adjust the gap between the No. 1 clamping frame 3 and the No. 2 clamping frame 6 to clamp metal materials of different sizes. The outer side of the screw rod 10 is symmetrically provided with positive and negative thread patterns. The screw rod 10 is threadedly connected to the side clamping plate 12.
